How accumulator odds combine
An accumulator multiplies the decimal odds of every selection together to get the combined price - so a two-leg acca at 2/1 and 5/4 (decimal 3.00 and 2.25) combines to 6.75 (23/4), not simply added together. The upside is a much bigger price for a small stake; the downside is that every single selection has to win, or the whole bet loses.
